To all 'whom t may concern Be it knownrthat I, TILLIAM J. P. Moons, acitizen o fthe United States, residing at New York', in' the county ofNew 'Ydrli and State of Nev:l York, have invented -stantially as will behereinafter described and then niorepartioularly pointed out in ing my.invention: Figure 1 is a vertical section of my iinprovedtension wheel;Fig. v2

which includes a brake drum'.v niiar characters of reference designatecorresponding parts throughout the different figures of the drawing. f

In referring to the particular style of and the use to which it is put,the View in Fig. 1 depicts my invention' as applied to a wheel to beused commonly the front W ieel, or driven wheel, .of an aut-o inobiie,the same having the hub 1, on whichis a cap 2, While 3 denotes the axle,and i the ball bearings Within the hub. The riin ol the wheel may be ofthe deinountable type, having cleiichersections 5, clencher band' 6,inner ring 7, perforated locking rings 40 and clamping bolts 8 forholding the parts'together in the usual Way. Ilt will be noted, however,that in the present appli catifui'l vani not laying claim to any of the.features of the deiiiountable rini, nor to the hub and aide mechanism,but only to the gnacing construction or plates or' disks and other paristhat lie between the hub and the' rim, which parts l shall now proceedto describe in detail. A'

In the combination shown i'n Fig. 1, I ernpioj/ two outer bent annulardisks 9, between which are tivopother cone-shaped annular disks 10.,Theinner'peripheral edges of these four disks are secured by bolts orrivets 11 to the flanges 19 on the inside .of hub- 1, there being washerrings 41 interposed between the outer heads of rivets 11 and theadjoiningedges oi the disks, into which washer rings the rivet heads arecouiitersunk; While the outer peripheral edges of disks 9 and l0 aresecured by the bolts or rivets 13 to the lianges 14 on the inner ring 7of the deniountable rim, Washer rings 42 being similarly insertedbetween heads of rivets 13 and the disks. The outery annular disks 9 arebent, as already stated, the bending being near Ythe middle points oftheir radii, so that their outer portions 9 lic substantially parallelto each otlier,'

While their inner portions 9* are flared to Ward the hub. The innerannular disks 10 ,are cone-shaped, theA apexes of their conicalforms-being near the middle points of their radii and opposite thecentral bent portions ofthe outer disks 9.

. Through the bcndings of' the outer disks 9 andthe conical centralportions'of the inlner disks 10 pass clamping' bolts-15.'. These boltshave at their central pointsan inte-V gral collar 15a, which liesbetween the contiguous apexes ofv the two conical disks 10.' The bolts15 are screw-threaded from end to end. Against the conical disks 10 andinside thereof at points on the other side ofsaid disks from where `thecollars 15a are located, l place washer rings 1G and,` against thesewasher rings, nuts'l'? having slots18 are screwed up tigl'itly so as topress the Washers 16 toward the disks 10 and toward the collar 15a untilthe requisite tension is secured. Also nuts 19, having internallyscrentlireaded passages, pass through openings in the outer disks 9 andengage the opposite ends of the bolts 15, said nuts 19 having slots 2Oin the outer ends thereof by which they1 may be handled with a screwdriver or a wrench, and further, it is found .convenient to interposewasher rings 21--be tween the flanged .outer ends ofthe nuts 19 and theadjacent faces of the disks 9. By screwing the nuts 19 tightly upon theends of the' bolts 15, the disks 9 will be forced inward with firmnessand under suliicient tension, the washers "l furnishing av goed bearingbetween tmc nuts 19 and the disks 9 and serving to distribute thetension uni*A formly throughout the disk. In the assembling of theparts', therefore, che nuts 1'? v-:ill first be screwed toward theWashers Cri and tion of ell the parts, inasmuch as the ri onical annulardisks 10 rve bracing,r members for the outer disks 9, and as :ill fourdisks are secured to the hub and to the rim, the .effect of the centrallot-kin? nieehiinisiu will be to ineke a very strong 'wheel having itsthin web ineinhers entirely in tension.

. The const 'uetion I have just'been. describing is shown in Fig. 1 andapplies to the driven wheel, commonly the front wheel, and not the oneordinarily equipped with a brake drinn, but in Fig. I have delineatedembodiment of. the same mechanical members in form vof wheel eonimonl51adapted nse rear Wheel and contain` ing a brake drum, hi le shoes, etc.ln Fig. 2, 23 denotes the drivingl shaft, Q'ithe hail bearings, theaxle, and 25 the hui cap, which parts are arranged and relateiii in anydesire-:l manner. represents 'the brake drum and heb. The drinn isadapted to contain brake parts, as fr instance the sho 26, while theinside opening into the drinn is covered by the side disk or plate 2". The rim 1 is the saine as that shown in Fig. 1, wherein a specimen ofdemoiintable rim is illustrated consisting of the cienclier sec-V tions5, clenchei' band 6, inner ring 7, clamping rings '10 and a series ofremovable elan'iping boltsS, said inner ring 7 having peripheral flanges14. The mecl'ianisn'i .connectingr the rim :ind the brake drum issimilar to that shown .in Fig. l, but consists of smaller parts thedistance between rim 1j-d drum is shorter, but the parte :ire ar--fnggil and brought under tension in suh- S" m'tijv he :fune manner.They comprise 14,5 @Mgr mdpvdisks 27 bent near the middle 3ii-fa1iid dieinner conical annular disks 28,A the o whose 0011681180@ 63011 othernear the middle 'part of the disks. The inner peripheral edges oftheonf-er disks 2i, as well as of the inner disks 2S, are riveted orbolted to the ianges 30 on the inner edge `of the brake drum 22 by meansof suitable eral ed of boite 13,

rivets or bolts 2i), there being washer rings 31 interposed between theheads of the rivets 29 and the adjni'ning edges o f the disks ".47, saidWasher rings 31 being suit-ably countersunk so that the herds of therivets 29 may lie therein flush with the outer surfaces oi. these rings31.

At the apen...- of the conical inner 'disis and the bendings ein' theter bent annular disks, 1 employ the Same ies of nuts,l washers andconnecting heirs, I have shown in Fig. 1, the bolts 15 each* having a'centi-ral eellar 15 which lies between the coni tuberences of the innerannui'ar disks' 28, while Within said disk, that is 'to say, on. theopposite side thereof from the cellar 15a vare w'sher ifi-rigs 16, thenuts 17 on bolts 15,. while on the outer ends of the bolts 15 are nuts19 having' S'ots 20 'therein and having screw-threaded pass-geseiigagingthe screW-threa ld ends of the bolt 15, there being interposed betweenthe outer headsA of theseniits 19 and the adjoining walls of thebenteiite-r annular disks 2"?, washer rings 21, the operation and effectof these parts being the saiiegas in Fig. 1 in giving the proper tensionte the wheel througii the thin web members.
